Abstract：
Due to the presence of extra top quark T in the little Higgs model, the CKM matrix is not unitary and the flavor changing neutral currents may exist at the tree level. We discuss the possibility of detecting the flavor changing signals of the Littlest Higgs(LH) model at the high-energy linear e⁺e^－ collider (ILC) via the processes e⁺e^－→tc+tc and e⁺e^－→WWν_eν_e→(tc+tc) ν_eν_e. We find that the resonance production cross section for the process e⁺e^－→tc+tc is significantly large, which can be detected in the future ILC experiment.

We discuss the possibility of detecting the flavor changing signals of the Littlest Higgs(LH) model at the high-energy linear e⁺e^－ collider (ILC) via the processes e⁺e^－→tc+tc and e⁺e^－→WWν_eν_e→(tc+tc) ν_eν_e. We find that the resonance production cross section for the process e⁺e^－→tc+tc is significantly large, which can be detected in the future ILC experiment.
